Answer 1

It seems to me that the system kill activity 2 and thus 2 is not in the stack anymore, thus it is now created anew and on top of 5. Thus when you back press you will get 5. A work around (I am not sure it will work) is as follow

1. When starting activity 4 from activity 3 and activity 5 from 4 use startActivityForResult.

2. In activity 4

   @Override
   protected void onActivityResult(int requestCode, int resultCode, Intent intent)
   {
       super.onActivityResult(requestCode, resultCode, intent);
   
       if (resultCode == RESULT_OK)
       {
            setResult(RESULT_OK);
            finish();
       }
   }  
   

3. In Activity 3

   @Override
   protected void onActivityResult(int requestCode, int resultCode, Intent intent)
   {
       super.onActivityResult(requestCode, resultCode, intent);
   
       if (resultCode == RESULT_OK)
       {
            new Intent(getApplicationContext(), 2.class);
           intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
           startActivity(intent);
            finish();
       }
   } 
   

4. In activity 5

   setResult(RESULT_OK);
   finish();
   

Answer 2

if you are going back from any activity to last activity.

please use finish() instead of creating new Intent

IN your code ,you are creating new Intent for activity 1.class,which is already exist .this is wrong

Intent dashboard = new Intent(getApplicationContext(), 1.class);
                dashboard.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(dashboard);

do this on button click

finish(); //this will finish your current activity which is in stack.

and try to use this or current activity name instead ofgetApplicationContext()`.

update : if you want to go any activity just use StartActivityForResult()
